RELEASE SCOS 2.5.7

New Features

New link reflection mode for the SCE 2000: Link Reflection on All Ports Linecard Aware

In SCOS 2.5.7, a new mode has been added to the link failure reflection functionality of the

SCE 2000: All Ports Linecard Aware mode. This mode is used when each link of the SCE 2000

(Subscriber-side interface and the corresponding Network-side interface) is connected to a

different linecard.

This mode reflects a failure of one port to the other three ports of the SCE 2000, in the

following manner:

• One interface of the SCE 2000 is down, indicating a problem with the SCE platform: Link

failure is reflected to the other three SCE platform ports.

• Two reciprocal ports of the SCE 2000 are down, indicating a problem in the linecard to

which the SCE platform is connected and not the interface: No action is taken. This allows

the second link in the SCE platform to continue functioning without interruption.

Resolved Caveats

The following caveats were resolved in this release.

Failure of Subscriber Database Loading from Disk

The operation of loading the subscriber database from the SCE platform internal disc may fail

when a burst of pull requests is initiated by the SCE platform after the connection with the

Subscriber Manager is established.

This issue is fixed in SCOS 2.5.7.

SCOS SW Upgrade Failure of SCE platform in Cascade Topology

During a SW upgrade of a cascaded SCE pair, the SCOS enters failure mode when three

consecutive reboots of the SCE platform occur within 30 minutes.

This issue is fixed in SCOS 2.5.7.

Failure of the Connection with the Subscriber Manager

In some rare cases applying a SCAS BB configuration file to the SCE platform causes the

connection with the Subscriber Manager to fail.

This issue is fixed in SCOS 2.5.7.
